Carbon Steel Welded Stud Finned Tube
Carbon steel stud finned tubes are industrial heat exchange elements that use carbon steel as the base tube and fin material. Fins (often in a stud-like structure) are securely welded to the outer surface of the base tube using high-frequency welding technology, thus forming an enhanced heat transfer surface.
- Base Tube Material:
CS (A106, A333, A179, A210, P5, P11, P22)
SS (SS304, SS316, Duplex SS2205, Super Duplex SS32750)
Nickel Alloys (825, Inconel Alloy 625, High chrome high nickle incoloy alloy Monel 400) - Tube OD:15.88mm~273mm or customized
Features of Carbon Steel Welded Stud Finned Tubes
Stud-shaped fin design and high-frequency welding process. The stud-shaped fins increase the heat transfer area to improve heat transfer efficiency, while high-frequency welding utilizes induction heating to achieve a metallurgical bond between the base tube and the fins, eliminating contact thermal resistance and ensuring high connection strength, thermal shock resistance, and vibration resistance.
The carbon steel material provides advantages such as low cost, high strength, and good pressure resistance, making it suitable for industrial radiators, boiler air preheaters, waste heat recovery systems, and other applications, especially in heat exchange equipment where a balance between economy and durability is required.
Applications of Welded Stud Tubes
Welded stud tubes have a wide range of applications in the petrochemical industry. Particularly in the convection chambers of tubular heating furnaces, resistance welded stud tubes are often used as heat transfer elements to enhance heat transfer on the outside of the tubes. Resistance welded stud tubes can increase the heat transfer coefficient on the flue gas side. The surface area of resistance welded stud tubes is 2 to 3 times that of bare tubes. With proper design, the same heat intensity as radiation can be achieved using resistance welded stud tubes.
The equipment used by Datang to produce resistance welded stud tubes typically employs resistance welding. The welding process is controlled by a PLC program, and the feeding motor and indexing use servo motors. The human-machine interface allows setting the number of studs, indexing parameters, and compensation coefficients, ensuring product quality and precision according to process requirements.

Carbon Steel Welded Stud Finned Tube Appearance Dimension Inspection
Carbon steel welded stud finned tube appearance dimension inspection is one of the important links to ensure the quality and performance of fin tubes.
The inspection items mainly include fin height, fin spacing, fin thickness, base tube wall thickness and outer diameter, etc.
Welded Studded Fin Tube Manufacturing Machine
The stud tube manufacturing equipment is a specialized device used for welding studs onto the surface of heat transfer tubes. Its core function is to create a dense structure of studs on the tube surface through resistance welding, thereby increasing the heat transfer area and enhancing the heat transfer effect on the flue gas side.
